Training visual efficiency in myopic persons

Twenty-four myopic college students were paired into groups based on degree of visual impairment using the Snellen Illiterate E. One member of each pair was then assigned to a no-treatment control group or a training program composed of fading, social reinforcement and performance feedback. Results on trained stimuli (Snellen Illiterate E) were significantly different across experimental conditions at posttest while differences across experimental conditions at posttest on untrained stimuli (Snellen Letters) were not significant. The implications of these data are discussed with reference to areas for additional research.     

Independence training vs modeling procedures for teaching phone conversation skills to the mentally retarded

Forty-five mildly mentally retarded adults were assessed for deficits in telephone conversational skills. They were ranked on the basis of their pretest scores and matched into triplets on skill level. One member from each of these groups was then randomly assigned to either a no-treatment control group, a modeling condition or independence training—a treatment that incorporated social reinforcement, instructions, performance feedback, modeling, shaping by successive approximations and self-monitoring and evaluation. For the two latter conditions, treatment was provided three times weekly for 2 months in group sessions (N = 5) of 1 hr duration. The dependent variable, conversational skills of subjects was assessed at pretest, posttest and at a 3-month follow-up based on verbal responses that subjects made to nine questions asked by an experimenter and related social responses during a phone call. Independence training proved to be significantly more effective than the other two experimental conditions at posttest and follow-up. In addition, modeling proved to be significantly more effective than the no-treatment controls at both of these assessment points.     

The Hong Kong version of the Oxford Cognitive Screen (HK-OCS): validation study for Cantonese-speaking chronic stroke survivors

This study reports the validation of the Hong Kong version of Oxford Cognitive Screen (HK-OCS). Seventy Cantonese-speaking healthy individuals participated to establish normative data and 46 chronic stroke survivors were assessed using the HK-OCS, Albert’s Test of Visual Neglect, short test of gestural production, and Hong Kong version of the following assessments: Western Aphasia Battery, MMSE, MoCA, Modified Barthel Index, and Lawton Instrumental Activities of Daily Living scale. The validity of the HK-OCS was appraised by the difference between the two participant groups. Neurologically unimpaired individuals performed significantly better than stroke survivors on the HK-OCS. Positive and significant correlations found between cognitive subtests in the HK-OCS and related assessments indicated good concurrent validity. Excellent intra-rater and inter-rater reliabilities, fair test–retest reliability, and acceptable internal consistency suggested that the HK-OCS had good reliability. Specific HK-OCS subtests including semantics, episodic memory, number writing, and orientation were the best predictors of functional outcomes.     

Head and Trunk Movements During Turning Gait in Children with Cerebral Palsy

Thirty children with cerebral palsy (CP) and 22 typical developing (TD) were tested with 3D-gait analysis. At turning, trunk rotation was larger in CP2 (GMFCS II) than in TD and CP1 (GMFCS I), and head flexion was larger in CP3 (GMFCS III) than TD. Maximum head and trunk flexion values during the entire trial were larger in CP3 than in the other groups, and trunk flexion was larger in CP2 than in TD. Trial time increased with GMFCS-level. Less trunk rotation than TD and CP1 reflects spatial insecurity in CP2, which in CP3 is compensated by the walker. The flexed head and trunk in CP3 and trunk in CP2 may reflect deficits in proprioception and sensation requiring visual control of the lower limbs.     

Recognition and personhood: A critique of Bernstein's account of the wrongfulness of torture

J. M. Bernstein argues that to capture the depths of the harm of torture, we need to do away with the idea that we possess intrinsic and inviolable worth. If personhood is inviolable, then torture can inflict only apparent harm on our standing as persons. Bernstein claims that torture is a paradigm of moral injury because it causes what he calls “devastation”: The victim experiences an actual degradation of his or her personhood. Bernstein argues that our value is given to us through mutual recognition and hence can be lost. In this paper, I argue that if our human value can be lost, then it first must be built up. If it must be built up, then the question of our status before the building begins must be answered. Bernstein faces a problem of human beings who fall outside relations of mutual recognition and hence are valueless. His best option for answering this problem is to point to the centrality of the body in his account of recognition, but doing so reveals a notion of intrinsic worth implicit in his account. I call for a revision of Bernstein's account that can hold on to devastation without eschewing intrinsic worth.

The factor structure of the Beck Depression Inventory-II: an evaluation

The Beck Depression Inventory-II (BDI-II) is a frequently used scale for measuring depressive severity. BDI-II data (404 clinical; 695 nonclinical adults) were analyzed by means of confirmatory factor analysis to test whether the factor structure model with a somatic-affective and cognitive component of depression, formulated by Beck and colleagues, has a good fit. We also evaluated 10 alternative models. The fit of Beck's model was not good for all criteria. Three of the alternative models had a better fit in both samples, but none of these met all criteria for good fit. Of the alternatives with a better fit, we selected the only model with unidimensional subscales, which assesses a somatic, affective, and cognitive dimension. For this model, which we recommend, as well as for Beck' original model, a good fitting structure containing 15 and 16 items was developed with an item-deletion algorithm.
